The crypto world is full of legends. Some go all in and end up with nothing, while others steadily build and tenfold their gains.

Today, let's talk about a proven "slow in, quick out" rolling position strategy. Basically, the core principle is two words: survive.

**Level One: Choose the Right Coins**

It's either a rise or an opportunity—you need to learn how to pick them—

Breakouts + volume increase are the real signals. When ARB hits $1.2, with trading volume surging 60% compared to the previous day, that’s a valid sign. Looking only at daily limits isn't enough.

Focus on the leaders, don’t be greedy. For Layer2, stick with ARB and OP; during the MEME season, watch DOGE and PEPE. Don't get dragged down by irrelevant altcoins.

Market cap should be between $300 million and $8 billion. Too small can be easily manipulated; too large is hard to move.

I personally never hold more than two coins at once. Concentrated efforts lead to better decisions.

**Level Two: Rolling Position Rhythm**

Using 200,000 USDT as an example:

Make the first move with only 60,000 USDT to test the waters. Wait until a key breakout with high volume before acting. Like PYTH when it stabilized at $0.8, set an 8% stop-loss and go in—don’t get entangled.

Take 40% profit and add 80,000 USDT. Once the trend is confirmed, increase your firepower to maximize profits.

After doubling? Invest the remaining 60,000 USDT entirely. Remember: never add to a losing position; only go all-in when you're winning big.

**Level Three: Risk Control Is the Key**

Never allocate more than 30% of your total portfolio to a single coin. After doubling, immediately take some profits and switch to USDC to lock in gains.

Set stop-losses no more than 6% of the total portfolio each time. Don’t listen to those saying "wait for a rebound."

Last year, I doubled my holdings and immediately withdrew 100,000 USDT. The remaining profits kept rolling.

**Real Case**

A friend who communicated with me started with 8,000 USDT, strictly following the rule: "Cut when down 5%, take half when up 20%." In less than half a year, he grew it to 150,000 USDT.

In the end, making money isn’t about secrets but about execution. Stay calm during crazy markets, and keep planning during panic.

The biggest test in crypto isn’t catching opportunities but resisting temptation. Pay less attention to K-line charts, do more research. Slow is fast.
